I am so behind on fic reading, I don't know how this happens! Anywhoo, two recs for you on this pretty Sunday...
Project Runaway by emerald_angel9 -- (Jared/Jensen, NC-17, 50,000 words) -- This fic is a take-off on Runaway Bride. It's layered and detailed and scorching hot. The lust and love is off the charts. I was so invested in these characters that I had a minor debate about even reading the last bit because I wasn't sure I could handle the conflict that was coming their way. *wibble* But! They are obviously destined for a happy ending! This is long but it reads fast so check it out.
Phthonus in Lethe by leonidaslion -- (Sam/Dean, NC-17, 6,094 words) -- Sam is jealous so he stakes his claim on Dean, in public. This is the possessive, bossy Sam that is my faaaavorite. And the care he takes to make sure Dean is in it every step of the way just sets off all my bells. Add in dirty talk, nervous!Dean, and Sam shoving Dean against a wall and I am DONE!
And then, go here and vote for Sam and Dean. THIS IS SERIOUS HOTTIE BUSINESS! I love me some Lucas and Nathan, but not more than Sam and Dean, so don't let them beat our boys, yeah?
